Combine ricotta, goat cheese, heavy cream, ½ teaspoon of the orange zest, salt and pepper in the bowl of a food processor. Process until completely smooth. Scrape into a small bowl. (Alternately, beat with a wooden spoon until as smooth as possible. Mixture may remain a bit grainy, which is fine.)

To assemble, spread ricotta mixture on toasts. Top with 1 or 2 strawberry slices. Sprinkle with remaining orange zest, black pepper and a drizzle of olive oil. Serve immediately.
